` OILING- DEVICE.

.Application filed March 1, 1926. Serial No. 91,353.

My invention relates to lubricating devices and has for its object to provide a new and compact grease or oil gun which is to be secured at some convenient place on, and by which differentpaijts of machinery may be independently and 'quiclgly oiled without the inconvenience to the operator of reaching to places diiiicult to oil and withoutsoiling the clothing andhan'ds of the oiler.

These objects I accomplish with .the-device illustratedy in the accompanying drawings in which similar letters and -numerals of reference indicate like parts throughout the several views, and as described in Lthe specification forming a part of this applica- -tion and pointed out in the appended claims.

In the drawings in `which I have shown thebest and most preferred embodiment of my invention, Figure 1 is a longitudinal section on line 1-1 of Figure 2. fFigure 2 is an end elevation ot the device. Figure 3- p is an end elevation of the sleeve plug. Figure 4 is a'transverse section on line 4 4 ot Figure 1, ,with partsi cut away and other parts shown in dotted lines, an'd showing one distributing tube in elevation.

` I have shown in the drawingsrthe hollow, handle A having one end portion A2 slid able on and within a portion of a member B and fastened on said member \by the splined key AB. A spiral spring 1 is carried on the handle A. A cylindrical casing B1 is carried between said spring 1 and a cylindrical casingl B3, which is a portion of the said member B. A plunger or piston C is closely fitted within said member B and is secured at one end to said handle A, and is suitably packed to prevent leakage of the oil. An inwardly flanged cylindrical-casing D is secured to a disk plate E bythe tap screws 2, and which casing is connected with a portion of the member II. An in dex plate F, having a pointer 3 formed thereon, is secured on thev end of. said member B. Numerals from one upwth legends, are shown on the outer face of said disk plate E. The said tap screws 2 arev passed through the instrument board G, of the mechanism to be oiled, to secure the device rigidly in place. A member H is carried pn the inner end of the member B,.within which member I-I the inner end portion of the member B is movable. The bearings for said movement are shown at Xf'iidY. A central bore 4 is provided within the member4 B, somewhat larger than the piston chami'ied and operated.

ber, vand within which a ball valve 5 is operated. The said ball valve 5 is noi'n'ially held in place by the spring (i which is. also carried in said bore 4. IVithinla radially. disposed hole 7 the casing J is carried, and which is transversely bored, at 8, and with# in which bore the ball valve 9 and its spring l 1U are carried and operated. yAnother transwei-se bore 11 is provided in said member B,

and within which the ball 12and its spring 13 are carried and operated. The said meniber H is transversely bored, as at 14 and 15, to 4form loil conduits, and within-which bores the ball 16 and the spring 17 are car-y A spring 2O isV carried on the member B cetween a shoulder 21 formed on said mem ,ber and the adjacent member H to allow cured to said member I-I, and with anotherA portion of said Casing24 formmgthe said I bearing X for the member B. yThe egress opening of the bore-8 is given a cone shape to form a seat on its inner side for tlrcball 9, and a tapered frusto-conically shaped*v outer face 40 which seats in the plug.28 when the cone shaped portion 40 is moved into contact with the seat formed portion 28a of the sleeve. plug 28by pushing the member B toward the member H. IVhen said contact has been made by said movenient the ball 9 will be moved out of its seat by the central portion 30 of the sleeve plug 28. In the face of said member H a plural ity of recesses 25 are formed within which the ball 12 is adapted to engage, and which recesses are spaced ,apart and positioned in a circle concentric with the axis of the member. Other circular recesses 26 are cut in the fac-e of the member H concentrically spaced from each other and from the recess 25 to form oil ports through' said member HN A plurality of tubes 27 are secured in the rear face of said member H, each of which leads `to or is connected with a portion of the low the oil to flow through the conduit lil. A central portion 30 of the sleeve plug 28 1s on the plane of the inner face of said memi* when the bore 8 and any one of the bores 15 are in alinement. In that position the ball 9 willr be unseated by pushing the member B,

which carries said ball 9, toward the member I-I. The said member B has its bore enlarged, as at 31, to receive the sleeve plug 32, which plug forms Vthe seat for the ball valve 5. lVitliin the said bore 31 a packing sleeve 33 is carried on the spring 34. The said spring is held with said bore 31 by the aching nut 35 which is screwed into said 'ici-e, and through which the oil supply is drawn by the suction of the piston C.

The operation of my device is as follows:

The oil is drawn through the bore .llb'y the suction of the piston C, as indicatedby the arrou7 a. The suction of the pieton C will raise vthe ball valve 5 and compress the spring 6 until the conduits 7 and Bare filled by the movements of the handle A. .The handle A and member B are rotated on the member H and its connected elements until the index pointer 3 indicates that the centering ball 12 is seated in the desired recess '25, which position is indicated on the disk plate E. The handle A is pushed towaid the instrument board Gr and compresses the spring 1. 'lhe oil Within the bore fr will be forced through the bore; in the casing J and com pressthe springs 23 and 17 and force the oil around the balls 22, 9 and 16 and -through the tube 27 to the desired place requiring lubrication. The device may be rotated to other positions Where the ball 12 is inthe recess 25 indicated as in alinement with tube 27 which connects with the place to be lubricated, and when the handle-is operated the oiling will be repeated for that place.

Having thus described my invention, I desire to 'secure by LettersjPatent and claim:

1. An oiling device comprising a dial plate adapted to be secured on the mechanism to be lubricated; a rotatable handle longitudinally slidable through said plate, and having a longitudinal central bore therein; aV

plunger operableuvithin the bore of said 'y handle; a fiange'd member Within Which said handle is Operated and Within which a portion of-said plunger is operated; anoil conduit radially bored in said member; a ball valve operable .in said 'radial conduit; means to seat said ballvalveghmeans to position-said conduit; an 'oil port4 cut'in' said flanged ,meml

ber and connected with said radial conduit; 'y

'member connected with said pump and having a radially disposed oil conduit bored therein; means to regulate the flow of oil through said member; a distributing mem# ber secured to said dial plate and having a plurality of oil conduits bored' therein.; valves to regulate the loW of oil through said conduits; and oiling tubes in connection with each 'of the last mentioned conduits.

In testimony whereof I have affixed my I signature.
